If no, try a new battery. Make sure that it is a good one and not a cheap knock off like you see on eBay and elsewhere. And don't let it run down below 20% on a regular basis.
Actually, about 1-2 months ago I kept my Blackberry in my bag and it was raining, and the rain got through the bag and in the Blackberry, but now it's in perfect condition until this incident.
So do you think I should buy a new battery?
